1. Prepare the Cake Batter:
In a large bowl, combine the cake mix, water, oil, and eggs. Beat on low speed for 1 minute, then increase to medium speed and beat for an additional 5 minutes. Once well combined, pour the batter into the prepared pan.
2. Prepare the Oven and Pan:
Preheat the oven to 180°C (350°F). Line the baking tray with baking paper, or grease the pan. Optionally, flour the pan or spray it with nonstick cooking spray.
3. Bake the Cake:
Bake in the preheated oven for 25 to 35 minutes. The cake is done when a toothpick inserted into the center comes out clean.
4. Cool the Cake:
Allow the cake to cool in the pan for 5 minutes before removing it.
